want a portable hard drive enclosure, need help.

I think it'd be pretty safe to say that it'll at least handle drives up to 137GB, and even if current rates of density increase continue (it's been slowing down quite a bit recently) it'll be several years before notebook drives get to that point.

As for weather it'll be able to handle drives bigger than that, it depends on the firmware. My offhand guess would be no, because it'll be so long before there's a necessity for notebook drives, but it's possible. You could ask them.

First think about power...

I've recently (and stupidly) bought a USB2 external drive caddy, thought it would suit me for my moving out and about....wrong.

USB2 can only push 0.1A over the host power, and my 2.5" HDD needed 0.5A. Thank god the caddy cost me £10 and the HDD was free.

If your buying a all in one solution that maybe fine for host powered over firewire, but just check first, main reason i bought my caddy was for portable without a external transformer.
